With his patented shave-and-a-haircut rhythm (it even bears his name), Bo Diddley was one of the most important and influential artists during the early days of rock & roll. This set collects -- in the original mono versions -- both the A and B sides of his singles for Chess Records between 1955 and 1959. Not everything is here (“Road Runner,” for instance, one of his most enduring releases, is absent), but there’s enough to make this a pretty good set.
